Fig. 1. (A) Quantitative cellular uptake of all synthesized peptides obtained in the alanine-scan represented as mean values. HeLa cells were incubated for 30 min with 20 μM peptide solutions. For comparison, the significance between the internalization efficacy of the most outstanding red labeled peptides was determined by students t-test (*p < 0.05; ***p < 0.0005). (B) Flow cytometry fluorescence intensity distributions of HeLa cells treated with HK3, HK15 and HK17.
